Concrete coring in Edmonton

The Process of Concrete Coring

Walser Contracting Ltd. provides what many might consider a unique – and strange sounding – services for interior and exterior renovations for commercial and residential customers in Edmonton and the surrounding area. That is, unless you’re in the construction business or have an engineering background. One of the questions owner Michael Podolak gets asked frequently is about concrete coring – like what is it and how is it used?


Concrete coring is the term that is sometimes used to describe the creation of a solid concrete building center; is sometimes loosely used as a term to describe professional concrete removal; and, like at Walser Contracting Ltd., concrete core drilling (or concrete coring) is the process of removing a cylinder of concrete from the rest of the structure. 


Concrete coring utilizes a diamond cutting drill to cut a perfect round hole in any concrete structure - in a floor, wall, or ceiling. The process is low-noise, dust free and non-percussive, meaning it is the most popular choice when it comes to cutting. Concrete coring uses a drilling tool made with a diamond cutting end attached to a steel tube to pierce concrete. Holes can be drilled at any angle – whether vertical or horizontal, and a choice of electric or hydraulic rigs can be used for drilling in sensitive locations or confined spaces. As the rig drills the cutter is cooled by water in order to reduce friction. The cutting process is completed by the removal of the slug, leaving a perfect hole with no cosmetic damage or requirement for after care. 


There are many applications across a range of fields, including plumbing, electrical, drainage, HVAC, the creation of vaults and manholes, and structural testing, but in general it is used for utility penetrations - making way for water pipes, sewer lines, electrical wiring, air circulation, phone lines, and computer lines. Coring is necessary whenever there is a requirement for a hole through concrete.
